Family Chat is a chat app tutorial using the MIT CloudDB database component and the default Redis server at MIT. Family Chat lets developers connect several users in a live chat. Family Chat allows you and your family or friends to have a live chat provided all members of your circle have a copy of this app on their phone/tablets.

The app uses Responsive Sizing and designed on a Tablet.

You must test this on your Android device using Companion. CloudDB apps presently will not run in the stock emulator that comes with App Inventor 2. This is an Intermediate to advanced level Project. MIT component documentation is at CloudDB .

Here is an MIT tutorial for a simplified version

I hope the App Inventor 2 Community finds this tutorial useful.

Thank you for the app. I would to send messages only a single member of family. Is it possible?
Also can chat only work with users within a certain distance, i.e. a few meters?

Yes. A simple way to do it would be to code and modify the example MIT tutorial for a simplified version link. Click the link shown at the bottom of the tutorial.

It can work with for any two individuals who have the same compiled app so the answer is yes. Both you and the family member must have a working WIFI or DATA connection using their Android devices.
